BS ISO 28593:2017规定了按属性逐批检验的单次抽样方案体系。当前系统的所有抽样计划均为“零接受”形式，即如果样本中包含一个或多个不合格项，则不接受任何批次。方案取决于适当定义的平均输出质量限制（AOQL），其值由用户选择；对AOQL值的选择或系列中连续批次的大小没有限制。该方法确保到达客户或市场的总体平均质量从长远来看不会超过AOQL。交叉引用:ISO 3534-2:2006第2版（R10）ISO 2859-1:1999购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 28593:2017 specifies a system of single sampling schemes for lot-by-lot inspection by attributes. All the sampling plans of the present system are of accept-zero form, i.e. no lot is accepted if the sample from it contains one or more nonconforming items. The schemes depend on a suitably-defined average outgoing quality limit (AOQL), the value of which is chosen by the user; no restrictions are placed on the choice of the value of the AOQL or on the sizes of successive lots in the series. The methodology ensures that the overall average quality reaching the customer or market-place will not exceed the AOQL in the long run.Cross References:ISO 3534-2:2006 Ed 2 (R10)ISO 2859-1:1999All current amendments available at time of purchase are included with the purchase of this document.
